Abstract
The invention relates to an electricity conducting material having magnetic properties constituted by an electronic conductive polymer in which are homogeneously dispersed permanent magnetic particles bonded chemically or physicochemically to the polymer or serving as a polymer dopant. This material can be prepared by the polymerization PA1 a) of a monomer such as pyrrole in the presence of a colloidal suspension of charged magnetic particles, or PA1 b) a monomer such as pyrrole, chemically bonded to a magnetic particle.
